[Safari 10 supports module, but not nomodule](/til/javascript/safari-10-supports-module-but-not-nomodule "Permanent Link: Safari 10 supports module, but not nomodule")

More and more of my own project uses <script type="module" src="app.js">, and for good measure, I tend to use [Parcel](https://parceljs.org/) (or [Rollup](https://rollupjs.org/guide/en/)) to compile a nomodule bundle that ships alongside the "regular" code.

Except, of course, Safari 10 doesn’t support nomodule. News to me, TIL.

So in this case the whole codebase gets run twice.

Thankfully a smartie has [a solution](https://gist.github.com/samthor/64b114e4a4f539915a95b91ffd340acc) to detect nomodule support.
